Application filed April 27, 19.211 Seriali-Ne. 4,833

.To all whom t may concern x lle it known that l, FREDERICK Centres, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Liquid-Coating Machines, of which the following is a. speciication.

This invention relates to the art of liquid coating and has special reference to a manually operable machine which l term a liq- 4uid applier and which is used for waterproofing and gumming the tops of paper containers or cans. f

@ne important object of the invention is to improve and simplify the general construction of devices of this character.

A second important object of the invention is to provide an improved and simple machine wherein both the water-"nooling or oil-proong and the gum may be properly applied to a can top without making it `necessary for the operator to hold the top or to soil his hands with the liquid to be applied.

A third important object of the invention is to provide an improved and simple machine arranged to enable a practically unskilled operator to apply water or oilprooling and gum to a paper can top.

lilith the above and other objects in view7 the inventionconsists in general of certain novel details of construction and combinations of parts hereinafter 'fully described7 illustrated in the accompanying drawings7 and speciiically claimed. i

ln the accompanying drawings, like characters of reference indicate like parts in the several views, and

Figure l is a plan view of a liquid applier constructed in accordance with this invention.

Figure 2 is a side elevation thereof.

Figure 3 is an enlarged detail section on the median plane of Figure 2.

ln carrying out the objects of this invention there is provided a pair of stands l() each of which carries a tank 1l, one of said tanks being for the purpose of receiving a water or oil proofing composition while the other tank receives a liquid glue or gum. rfhese tanks are connected in spaced relation by a frame l2. At each end of each tank is a suitable bearing 13. The bearings all being alined and through these bearings extents a shaft ldhaving on one end a drive pulley l5 so tha the shaft may be driven by a belt 1G. lt is, of course, obvious that other means of driving may be utilized. Within each of the tanks ll thereis fined oo to the shaft la a feed roller or drum l?. EX- tending diagonally outward from the frame are brackets i8 and at the outer end of each bracket is a pivotally mounted fork i9 between the arms of which is tiltably mounted a rod 20 carrying at its inner end a brush 2l, the outer rend of said rod being used` for a handle.

By means of this construction the brush 2l may be brought into contact with the re- To volving feed roller i7 of the respective tank or may be swung to any desired position away from such feed roller.

Extending forwardly from the frame l2 is a bearing boss 22 which is hollow and opens toward the rear of the machine. rlhrough this bearing boss extends a hollow shaft which carries on itsupper end a disk 24; provided with a centrally disposed recess in its upper face wherein feeds a stripper plate 2.3 mounted on an ejector rod 26 extending through the hollow shaft and provided on its lower end with a striking knob 27. Secured to the shaft 23 within the bearing boss is a spiral gear 2S which meshes S5 with a spiral gear 29 fixed upon the shaft 14.

ln the operation of the device the operator places on the disk 2da can top such as the top prepared by the die press illustrated and described in my copending application 9 filed the 27th day of April, i921, and bearing the Serial Number 464,833. lie revolution of the shaft la causes the lower peripheral portions of the feed roller 17 to constantly move upward and as these lower portions dip into the contents of the respective tanks `the upper portions of these feed rollers are coated with a thin film of the material to be appl'ed. The operator places the brushes on the feed rollers by proper manipulation of the rods 20. Next the brush for coating the top with lwater or oil-prooling is swung into position to lie on top of the paper can top or closure as shown in dotted lines in Figure 1. lt is to be noted that during the entire operation the shaft 23 is rotated by the action of the spiral gears. This rotation frictionally causes rotation of the can top beneath the nioistened brush 2l thus applying the liquid evenly over its surface. As

the water or oil-pirooiino is accomplished this brush is swung back to engagement with its feed roller and 'the other brush is nioved into position in the channel ott the can top as also shown in dotted lines in Figure-l. Vhis affects coating oi the entire inside ot the channel 'with the liquid adhesive. fitter this coating' is accomplished the brush is swung back to its t'eed roller and the operator, by smart tap on the striking knob Q'Ti disengagrcs the can top 'ii-oni the carrier disk 242. he can top inay ai be lifted oii' and another top put in po- Y,tion for further operation.

Tiefe has thus been provided a simple ei'ilcient device olf the kind described auf.) and i'or the purpose specified.

.it obviouA c .at minor changes n'iay be made ir. t' iorni and instruct-ion ot the invention witiiout d Waiting troni the matenciple i. llt is not therefore i to coi ine the invention to the exact torni Aierein shown and described7 but it is wished to include all such as piiuporly come within the scope claimed.

lilaving thus describe'. the inventioin what is claimed as new, is
